The Model 351 Jib Crane is designed with safety features to prevent removal of head under accidental impact.

Boom is an American standard I Beam or wide flange beam, that conforms to AISC and ASTM standards. Girder is equipped with removable end stops for quick trolley installation and maintenance. Bearing housing is rigidly mounted on boom.

The mast consists of a heavy pipe design to withstand bending stresses without undue deflection to boom. Assembly is jig welded to insure vertical alignment.

Jib crane head is constructed of two heavy sides and reinforcing plates to permit balancing of stress. Lower roller assembly is mounted in a heavy duty machined carriage weldment. Assembly is supported by adjustable tension bolts to permit field adjustment, and to insure even pressure of the rollers on the mast. Roller bearings are furnished in each machined roller and are mounted to the frame through removable steel axles with grease fittings. Top bearing is a tapered roller radial thrust bearing.

The HSI Model 351 Freestanding Heavy Duty Jib Crane is base mounted, but is also available foundation mounted and foundation sleeve mounted.

All structural steel will be painted with one coat standard safety yellow enamel, unless otherwise specified.

Jib cranes are the most cost effective and versatile type of lifting equipment. They are great for use in production lines to keep machining cells, workstations and warehouse production moving. Jib cranes also work well to aid larger overhead crane systems. Jib cranes are easy to install and cost effective, with less structural limitations than other material handling options.

Follow these basic guidelines to help you choose the correct jib crane for your application:

Capacity: Choose a capacity that is right for current and future lifting needs. Most of the available options at JibCranes.com, up to 5 tons, include a 15% allowance for the hoisting equipment. This allows for full use of the rated jib crane capacity.

Span: Choose a span that is adequate to cover the full work area. Keep in mind that hoist and trolley selection may reduce the end approach, limiting hook coverage and requiring a move to a larger span.

Hook Height: The hook height is the height needed to lift your material. This measurement is equal to height under boom minus the headroom of the hoist and trolley.

Rotation: Jib cranes, depending on their design, have between 180° and 360° of rotation. Be sure that the area of installation is free of obstructions throughout the full range of rotation. Rotation stops are available upon request to limit the range of rotation.

Supporting Structure: When selecting a jib crane be sure to take into consideration the supporting structure. Building structures must be able to support the forces of the jib crane and load. Please, consult with your building designer or an engineer if uncertain of the adequacy of supporting structures. Also, keep in mind that the foundation requirements of freestanding jib cranes will add additional costs.
